The smallest known pterosaur is Nemicolopterus with a wingspan of about 25 cm (10 in). [1] The specimen found may be a juvenile or a subadult, however, and adults may have been larger. Anurognathus is another small pterosaur, with a wingspan of 35 cm (14 in) and 40 g (1.4 oz) in body mass, [2] along with an indeterminate non-pterodactyloid ...
A paleo-population study is one of the most difficult of analyses to conduct in field paleontology. Here is the most recent estimate of the proportions of the eight most common dinosaurian families in the Hell Creek Formation, based on detailed field studies by White, Fastovsky and Sheehan.
